When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.
Examples:
80 km/h is a speed.
80 km/h due north is a velocity.
What else can I help you with?
What is it called when you describe an object's speed and direction?
When describing an object's speed and direction, it is referred to as velocity. Velocity is a vector quantity that specifies both the magnitude (speed) and direction of motion.
The term used to describe the study of motion?
The study of motion is called kinematics. It involves describing the motion of objects in terms of displacement, velocity, acceleration, and time without considering the forces causing the motion.
What three things do you need to now to describe the velocity of an object?
To describe the velocity of an object, you need to know its speed (magnitude of velocity), direction of motion, and reference point for measuring the motion.
What are kinematic quantities?
Kinematic quantities are variables that describe the motion of an object without considering the forces that cause the motion. They include parameters such as position, velocity, acceleration, and time. These quantities help in analyzing and describing the motion of objects in a physics context.
What term can best describe both speed and direction of an objects motion?
That is called "velocity".

What is the term to describe motion when different observers see the same motion differently?
Relative velocity/motion
What are needed to completely describe velocity?
Speed and direction of motion.
What term can best describe both speed and direction of an objects motion?
That is called "velocity".
Term can describe both the speed and direction of an object's motion?
Velocity
What can describe both the speed and direction of an object's motion?
Velocity can describe both the speed and direction of an object's motion. Speed only describes how fast an object is moving, while velocity includes the direction the object is moving in as well.
What is the quantitative to describe motion?
Speed, velocity, and acceleration are common quantitative measures used to describe motion. Speed is the distance traveled per unit of time, velocity specifies both speed and direction, and acceleration measures the rate of change of velocity.
What term can be describe both the speed and direction of an objects motion?
Velocity. Velocity is a vector quantity that describes both the speed (magnitude) and direction of an object's motion.
